At first, putting them on was very rough and the gliding was stiff. But over time, using it got smoother and glides way better than the Viper Mini PTFE feet. Definitely worth it. Read more

works fine, just a bit stinky Read more

I highly recommend these feet for the Viper Mini. The problem with the stock feet for the Viper Mini is that they're not placed well, and even though they're pure PTFE, they're too thin. Due to how the bottom is shaped with the placement of the feet, there's some friction on the bottom of the mouse at times causing inconsistency in smoothness. Although these feet are not pure PTFE, they're nice and thick, so scraping against the bottom of the mouse is no longer an issue. They're also hard and more slippery/smooth than most stock dyed PTFE. However, I would NOT recommend these feet for the Viper Ultimate. The stock feet of the Viper Ultimate have good placement and they're pure PTFE. Since the Viper Mini has high lift-off distance, the fact that the feet are so thick work in its favor. It won't work in the favor of the Viper Ultimate, but these feet fix an issue with the Viper Mini. I would definitely recommend that Viper Mini owners upgrade their mouse feet to thicker ones, and these are a great option. Read more

I actually put these over the existing mouse feet, it puts my hand in a more confortable position, just make sure you put the lift of distance to the max in the Razer Synapse software!!! Read more
